Definitions

  • Gaskets are mechanical devices used to provide a leak-tight seal between two slightly irregular mating surfaces, such as an enclosure and its doors and accessories. In many indoor and outdoor applications, a properly mounted, well-performing gasket is critical to the protection of sensitive electrical and electronic equipment inside the enclosure. Gaskets can be used to exclude matter in the external environment such as dust, dirt, and water, from entering an enclosure.
  • Strip gaskets are a commonly used type of gasket for sealing enclosures. When installing strip gaskets, manufacturers may adhere rolls, or strips of a gasket to an enclosure surface and then cut the strip to an exact measurement. Strip gaskets typically have a single layer of adhesive on one side of the gasket which allows it to adhere to a desired surface. Because the gaskets were in a roll prior to installation, the gaskets may have a curved shape which can cause a void or space to appear between the strip gasket and a surface on which the strip gasket is applied. These voids or spaces can allow water or other particulate matter to enter the enclosure under the gasket.
  • multiple pieces of strip gaskets may be used to completely cover a desired surface.
  • this method of installation creates a seam in each corner or joint between the interconnecting gasket pieces. These seams may make the gasket more vulnerable to wear and damage over time.
  • Strip gaskets applied to enclosure doors during assembly at a manufacturing plant also tend to get stretched during the assembly operation.
  • the strip gaskets are placed into the enclosure doors and then cut to match tightly at the corners.
  • a tight fit between the pieces of the strip gaskets is critical in attempting keeping water or other particulate matter out of the enclosure.
  • Stretched gaskets will shrink to their original length over time, causing them to separate from one another. This separation allows water and other matter to penetrate under the gasket at the gasket joints. [0005] Therefore, there exists a need for a strip gasket which will not stretch, while also preventing water and other matter from entering under the gasket and into an enclosure.
  • Embodiments of the disclosure provide a strip gasket for an enclosure, the strip gasket comprising a base having a first surface, a plurality of adhesive strips on the first surface wherein a first adhesive strip includes a first adhesive and a non-stretchable carrier for the first adhesive and a second adhesive strip includes an second adhesive.
  • Embodiments of the disclosure also provide a strip gasket for an enclosure, the strip gasket comprising a base having a first surface, a single adhesive strip on the first surface where a first section of the single adhesive strip includes a first adhesive and a non-stretchable carrier for the first adhesive and a second section of the single adhesive strip includes an second adhesive.
  • Embodiments of the disclosure also provide an enclosure having a strip gasket, the enclosure comprising a body having a front surface wherein the front surface includes a first outer periphery portion, a door having an inner surface wherein the inner surface includes a second outer periphery portion, a strip gasket having a base section, a first adhesive strip and a second adhesive strip wherein the first adhesive strip includes a non- stretchable carrier, and wherein the strip gasket is applied along the second outer periphery portion of the door such that the strip gasket can come in contact with the first outer periphery of the body when the door is closed and abuts against the front surface of the body.
  • FIG. 1 is a perspective view of one embodiment of an enclosure with a strip gasket attached to the enclosure door.
  • FIG. 2 is a perspective view of a first embodiment of a strip gasket having multiple adhesive strips.
  • FIG. 3 is a perspective view of a second embodiment of a strip gasket having multiple adhesive strips.
  • FIG. 4 is a top view of a third embodiment of a strip gasket having multiple adhesive strips and a paper covering over the multiple adhesive strips.
  • FIG. 5 is a perspective view of a fourth embodiment of a strip gasket having a single adhesive strip with a non-stretchable carrier located in a section of the adhesive.
  • FIG. 1 illustrates one embodiment of an enclosure 10 having a body 20 and a door 30.
  • a strip gasket 40 can be applied to an inner surface 32 of the door 30.
  • the strip gasket 20 can be cut into precise dimensions to allow the gasket 20 to cover the outer periphery 34 of the inner surface 32 of the door 30.
  • the outer periphery 34 of the door 30 can be configured to mate with an outer periphery 22 of a front surface 24 of the enclosure body 20 when the door 30 is closed and abuts against the enclosure body 20.
  • the gasket 40 provides a seal between the outer peripheral surfaces 22, 34 of the body 20 and door 30 of the enclosure 10.
  • FIG. 2 illustrates one embodiment of a strip gasket 40.
  • the strip gasket 40 can be made of various materials such as foam, vinyl, synthetic rubber or silicone.
  • the strip gasket 40 includes a base 42 and a top surface 44. In one embodiment, the base 42 of the gasket 40 is solid.
  • FIG. 3 illustrates an alternative embodiment of a strip gasket 50.
  • the base 52 of the gasket 50 is hollow and can have an inner surface 54 and an outer surface 56.
  • the inner surface 54 of the gasket 50 is configured to provide a hollow cross section region.
  • alternative cross sectional shapes can also be used with the strip gasket 50.
  • the gasket 50 can have cross sectional shapes such as a round shape, a rectangular shape, a "figure 8" shape, a "C” shape, a "D” shape, a "P” shape or other shapes known in the art. These cross sectional shapes can be solid, hollow or a combination thereof.
  • the strip gasket 40 includes multiple adhesive strips 60, 62.
  • the strip gasket 40 can include a first adhesive strip 60 and a second adhesive strip 62.
  • the first adhesive strip 60 can be parallel to the second adhesive strip 62. However, the orientation of the multiple adhesive strips can be adjusted as desired by the user to provide a proper seal.
  • the first adhesive strip 60 can also be spaced from the second adhesive strip 62.
  • the first adhesive strip 60 and the second adhesive strip 62 can be proximate to one another with substantially little to no spacing between the first 60 and second 62 adhesive strips.
  • the first adhesive strip 60 includes an adhesive 66 and a non-stretchable carrier 68 for the adhesive 66.
  • the non-stretchable carrier 68 for the first adhesive strip 60 helps prevent the gasket 40 from being stretched. This helps prevent the gasket 40 from shrinking over time, which can cause one portion of the gasket 40 to draw away and separate from a surrounding portion of the gasket 40 at a gasket joint 41. This separation of the gasket 40 portions could allow water and other matter to penetrate under the gasket 40 at one or more gasket joints 41.
  • the second adhesive strip 62 works in conjunction with the first adhesive strip 60 to create a tight seal against a surface to which the strip 60 is attached. This tight seal helps prevent water, dust and other particulate matter from passing through and around the strip 40. Having a second adhesive strip 62 also helps ensure that the strip gasket 40 completely adheres to a desired surface. Therefore, even if there are voids or spaces created between the first adhesive strip 60 and a desired surface when the first adhesive strip 60 is installed, the second adhesive strip 62 ensures that water or other particulate matter will not reach these voids or spaces.
  • a user can apply the strip 40 such that the second adhesive strip 62 is applied proximate to an outer edge 36 of the door 30 and the first adhesive strip is applied proximate to an inner edge 38 of the door 30.
  • the second adhesive strip 62 can be applied proximate to an outer edge 36 of the door 30 to help prevent any water or other particulate matter from passing through or around the strip 40.
  • FIG. 4 illustrates one embodiment of a strip gasket 70.
  • the strip gasket 70 includes a first adhesive strip 72 and a second adhesive strip 74.
  • the first adhesive strip 72 and second adhesive strip 74 includes a first paper 76 and a second paper 78 to cover adhesive within each respective adhesive strip 72, 74 until they are ready for use.
  • the first paper 76 can be a different color from the second paper 78 to indicate to a user that one paper covers the adhesive having a non-stretchable carrier, while the other paper covers an adhesive only.
  • the first paper 76 can be colored brown to indicate that it covers an adhesive having a non-stretchable carrier, while the second paper 78 can be colored white to indicate that it covers an adhesive only.
  • the first adhesive strip 72 and second adhesive strip 74 includes a single paper to cover both adhesives within each respective adhesive strip 72, 74 until they are ready for use.
  • FIG. 5 illustrates one embodiment of a strip gasket 80.
  • the strip gasket 80 includes a base 81 and a top surface 83.
  • the base 81 can be solid or hollow.
  • the strip gasket 80 includes a single adhesive strip 82 and includes adhesive located on a top surface 83 of the base 81.
  • the single adhesive strip 82 includes multiple distinct sections.
  • the adhesive strip 82 includes two distinct sections on its top surface 83: a first section 84 and a second section 86.
  • the first section 84 of the adhesive strip 82 includes an adhesive 90 and a non-stretchable carrier 92 for the adhesive 90.
  • the second section 86 of the adhesive strip 82 includes an adhesive 94 which can be the same substance as the adhesive 90 of the first section 84 or can be a different adhesive substance.
  • the non-stretchable carrier 92 of the first section 84 helps to prevent the strip gasket 80 from stretching over time and the adhesive 94 of the second section 86 helps the strip 82 to completely adhere to a desired surface.
  • the second section 86 of the adhesive strip 82 also helps prevent water and other matter from entering under the strip gasket 80 because of the tight seal created between the second section 86 and a desired surface.
  • the single adhesive strip 82 can also include a paper 88 to cover adhesives 90, 94 within the first section 84 and second section 86 of the adhesive strip 82 until it is ready for use.
